Specification of Letters Patent.

L, Patented Oct. 13, 1908.

Application led December 9, 1907. Serial N o. 405,654.

To all 'whom t may concern:

Be it .known that I, HENRY S. BREWING- TON, a citlzenof the United States, residing at Baltimore city, State of Maryland, have invented certain new anduseful Improvements in Ash-Sifters, of.v which the follow-1 ing is a specification.

My invention relates to animprovement the object being to effectually separate from waste ashes the cinders which are available for consumptionV as fuel.

My invention has for itsobj ect to provide an ash sifter of a character to be hereinafter described in which the dust andash receptacles are so arranged and disposed that the sifting of the ashes can be accomplished in a very effective manner, and the receptacles may and emptied of their contents. A

My invention is more particularly an improvement upon the sifter heretofore invented by me forming the subject of-Patent No. 403,087, in that I have provided thevperforated circular plate forming the bottom of the pot with aseries of agitator blades and the walls of the pot are perforated as will be more fully described in the details of construction and arrangement of parts hereinafter described and shown in the accompanying drawings forming a part hereof, in which,

Figure 1, is a sectional elevation; Fig. 2, is a plan view with a part broken away to show the hinged connection; Fig. 3, is a plan view of the revoluble bottom, showing the 4, is a section on' agitator blades, and Fig. the line w-m of Fig. 3.

A, is a casing made of wood, but whichmay be of any suitable material, such as sheet iron or other sheet metal. In this case A are two drawers, land 2. The bottom of the drawer 2 is ashes when sifted down from the drawer 1, which has a wire sieve or perforated bottom 3, to allow the ashes to pass through and to, retain the cinders of coal in the drawer.

The top of the casing vA is formed on al hollow curve 4, as is shown in Fig. 1. Above the case A is another case B, made of the same material and conformable in dimensions horizontally to case A, and about the same' vertically. The bottom of case B is made convex to conform and fit in the concave top 4 of the lower case A.

On eachside of the case .A is a standard 5, which is secured to it by any ordinaryu mechanism and the be readily removedv 14 provided above the threaded made close to hold thev means at 6-6, and projects upward to near the top ofithe case B. The upper case B is pivotally secured between the standards 5, by means of the pivots 7 7, by which means the 'top case B is swung, the pivots forming the center line of the curve of the bottom ofthe case B, so that it can be swung upwardly as indicated by the dotted lines in Fig. 1; S is an ordinary latch or button by y which means the case B is vertically secured to case A, and `to prevent the case B from A swinging between the uprlghts 5.

Within the case B is secured a deep cylindrical pot C, made of metal, either sheet'or cast,the walls of which are perforated at 9, and provided with a revoluble bottom D, plate perforated lwhich bottom is a circular made preferably of cast asindicated at 9x, metal and having cast thereon a series of agitator blades 10, cast in the said bottom plate D near the outer edge thereof is a circumferential groove 11, into which is revolubly secured the pot C by the means of a vertical shaft 12, which extends through the center of the bottom D and is secured thereto Jby, ordinary means such as the end of the shaft being threaded at`13, and a shoulder portion, and a nut 15 screwed on the threaded portion, thereby'securing the bottom plate D between the shoulderl 14 andthe'nut 15. This shaft 1 2 passes through the top of the case B and has on its upper end a beveled pinion wheel 16, which meshes with a vertical beveled gear wheel 17, on a horizontal shaft 18, having on its outer end a crank handle 19. This shaft is sustained in bearings 20-20 on a frame 21, secured to the top of the case B. The upper end of the vertical shaft 12 is supported in a projecting Aextension or boss 22 ofthe frame 21,.

A lid 22X, formingfa part of the top of the case B is hinged to the top at 23, so that it can Vbe opened to pour the cinders into the pot C, and it also serves as the opening for the discharge of the cleaned cinders. 24 is a latch for securing the lid shut; 25 is a handle securedto the case B for the purpose'of swinging or turning the case; 26 and 27 are similar handles secured to the drawers 1 and 2 respectively, by reason of which `their insertion and withdrawalin and from the case A is facilitated.

The sifter is operated as follows: The cinders with the ashes are thrown into the pot C, when the lid 22 is raised, as indicated in dotted lines as shown in Fig. l. The lid is then let down and secured shut by means of the latch 2st. The handle 25 is turned a few times which causes the perforated bottom plate D to rotate and the rotary motion of the plate carrying thereon the agitator blades l0 tumbles the cinders and causes the ashes and other fine matter to sift through the perforated side walls of the pot C and the perforated bottom plate D into the drawer l, where it will fall through the wire screen or perforated bottom 3 into the close or ash drawer 2.

By means of the handle 25, on the side of the top case B, the case may be lifted up until the pot C is turned upward, the contents thereof will be discharged into the drawer l.

It has been found from actual demonstration that the perforations in the walls of the pot C, and the providing` of agitator blades on the revoluble bottom plate D, are absolutely essential to insure the effectiveness in operation necessary to the commercial success and sale of the device.

Having fully described my invention, what l claim as new and desire to secure by Letters Patent, is:
